To all whom itmay concern.- r a Be it known that I, J OHN A. KIMBERLY, Jr, a citizen of the United States, residing at Albany, county of Albany, State of New York, have invented a certain newand 'u'seful Improvement in Paper-Roll Holders, and declare the followin to bee. full, clear, and exact description 0 the same, such. as will enable others skilled in-- the art to which it pertains to makejand usethe'same, reference beinghad to the accompanying drawings, which form a part of this specification. a

This invention-relatesto paper roll tension devices and its obj ect'is to-provide a simple and efficient device for .placing a tension on the roll to prevent over-running of the roll during unwinding of paper therefrom, and whereby the withdrawn strip is continuously held taut; A further object 0f the invention is a tension device that'may be used without regardtothe di- "rection of rotation ofthe roll, operating with equal facility on' rotation in either direction'.: A further object ofthe invention rotatable and a tension device on the shaft engaging the inner surfaceofa plug or disk in theiroll-core, whereb certain strain is required to rotate the rol a objects and theseveral novel features of the invention are hereinafter more fully described and claimed and the preferred form of the device is shown in the accompanying drawin s-in whic -ma Figure 1 1s an elevation partly in section showing a paper roll as'mounted foruse'in a" printing andserving machine a portion of the machine only being shown:

Figsfll and 5 In the large part 6 of the shaft isa spring 7 extending-spirally about the smallend 5 of the shaftfand having one end fastened to the large end 6 .at 8.

The end 6 is provided with a rectangular end 9 which is adapted to fit within the 1 slot 10, in the bracket 11 which is secured small end5 of the shaft extends through the plug or disk 3 and is supported. in a bracket 12;,which is also securedtothe side of the printing and serving machine. As shown in Fig. 3' the bracket 12 is provided with an angular ;slot. 13 ending in a'slot let inwhich videsja lug 15 which prevents displacement o'f the roll whenrotated. I x Inoperation the shaft shown in Fig. *5, is

.placedwithin the rollin-the manner shown inFig. 4,,thespring 7 being compressed betweenitheplug orolisk 3 and theend of the -:the end 5 ofthe. shaft seats, the slots 13v and; r 1 4 beingprovided to allow the roll. and end 5 -.5 therein to beset in place in the bracket. ;The,arrangement of'the' slots .13 and '14 prolarge, part6. ,When the shaft is thus force-1 3- yieldably holds the .roll from. rotation.

a The )plug or disk 3 being stationarily;

mounted within the roll, rotates with the .rolland theshaftis held from rotation by the rectangular end 9 fitting the slot 10 in the bracket 11. Thus with the arrangement shown, the spring 7 tends to frictionally en a spring being secured to the shaft is thereby .held from rotation and by this engagement ."diske3 is increasedand by forcing the spring turns closer together the friction between vthe member 3 and the spring 7 is decreased sothat by this means the resistance to ,rota-, tion of the roll may be increased or decreased as the operator may desire. As shown'more particularly in dotted lines in Eigfl, 19 15 i difi rs t .vi lthsime b used the fric terial.

with the same shaft provided however that v the core openings in the rolls are of thesame diameter. A narrow roll is shown by use of the dotted lines 16. in Fig.2 and the: dotted line 17 representing the protruding portion of the lar eshaft end 6.. It can be seen more particu arly from Fig. 4 that the spring 7 forcing against the plug or disk 3 forces the plug or disk and roll to which it is secured tightly against the bracket: 12

so that the edge of the roll is always forced to position adjacent the bracket 12 by the sprmg'Z, the width of the roll bein imma- By using several rolls of ifi'erent widths and severalbrackets 12 in alinement within the. printing and serving machine the several sheets of different widths will always be served from the rolls in aline ment on one edge. This feature is particularly desirable m instances where a narrow sheetis used for the sales slip and the wider slip being used for a copy for the manufacturer or retailer and by this use of the Wider slip for the copies'the manufacturer or re tailer' is provided with a space or margin on V which to write instructions, notations,- etc., pertaining to that special order. It is to be noted that the resistance to rotation is not 'onl v'g pr'oduced by the friction of the spring 7 on the. plug or disk 3"but also'on account of theroll and plug being'forced'against vent anyispr'ing action of thesaid brackets. It is to be understood that thebrackets 11 and 12 need not be of the specific character des'cribed'but may be changed in design to conform to that of the device with which it is .used', the necessary characteristics of the roll support being that the shaft be held from rotation at one end and a support for the shaft be provided at the other end.

Without the use of a tension device the paper rolls of printing and serving machines frequently over-run causln'g undesirable loops in the withdrawn strip and frequently causing disarrangement of the SEV- eral paper strips ordinarily used in the i i V printing and serving machine. By the arrangement here shown such possibility is prevented.

For'the foregoing description it'becomes evident thatthe device is ofa simple nature,

is very efficient in operation and accomplishes the objects desired.

Having thus briefly described my invention its utility and mode of operation what i 'I claim and desire to secure by Letters Pat ent of the. United States is 1. Apap'erroll holder for printing and serving machines and the like comprising- "extends when ably preventing rotation ofthe roll.
